lviACHlNE FOR WINDING BOBBINS FOR LOOM-SHUTTLES.

SPECIFICATION forming part of Letters Patent No. 320,851, dated June 23, 1885.

Application filed July 12, 1883. (No model.)

T0 all whom it may concern:

Beit known that I, J OHN H. CROWLEY, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Machines for \Vinding Bobbins for Loom-Shuttles, of which the following is a specification.

The objects of my invention are to auto matically stop the rotation of any spindle when the bobbin which it carries has been wound full, to readily vary the angle of the presser-rollers for bearing against the yarn as it is wound upon the bobbin, and to provide a simple and automatic tension device for the yarn.

In the accompanying drawings, Figure 1 Sheet 1, is a transverse section of sufficient of a windingi'rame' to illustrate my invention; Fig. 2, Sheet 2, a side view, partly in section, on a larger scale; Fig. 3, a plan view of Fig. 2; Figs. 4 and 5, sections on the line 1 2, Fig. 2, the parts in one view being in a different position from those in the other view; and Figs. 6' and 7, Sheet 3, perspective views of parts of the device. Figs. 8 and 9, Sheet 4, represent slight modifications of parts of the invention.

A represents part of the frame of the machine, and B one of the windingspindles, of which, in an organized machine, there are a a number side by side, each spindle being provided with means for holding a bobbin, a, on which the yarn is to be wound, and being furnished with a drum, b, for the action of the driving-belt. In the present instance the drum rests directly upon abelt, d, which runs from one end of the machine to the other, as in my Patent No. 263,287, August 22, 1882, and may be driven by the means shown in said patent. The means for reciprocating the traverse-bar D may also be similar to those shown in the patent, and as these form no part of my present invention it has not been deemed necessary to illustrate or describe them. As the yarn is wound upon the bobbin, the spindle is caused to move rearward, owing to the action of the usual conical rollers, F, which press upon the conical end or nose of the mass of yarn wound upon the bobbin, these rollers also serving to effect firm and compact winding in a manner well known.

In order to insure the firm bearing of the yarn on the bobbin against the rollers F, Iar- ,range the axis of the spindle B at an angle other than a right angle to the line of movement of the driving-belt d, as shown, for instance, in Fig 3. In consequence of this the movement of the belt has a tendency not only to rotate the spindle, but also to propel the same forward with aforce proportionate to the degree of inclination of the spindle in respect to the belt.

In the patented device above alluded to the belt d used was a small round belt, and as the spindle was pressed rearward the drum left the belt and. the rotation of the spindle was stopped, the bobbin being by this time wound full. In the present case, however, I desire to use a flat belt; hence this plan of stopping the spindle is not advisable, and in carrying out my invention I adapt the rear portion of the spindle B to a slot, f, in the short arm of a lever, G, hung to a projection, g, on a plate, H, secured to the frame, the long arm of the lever being weighted. \lhen the yarn is being wound upon the body of the bobbin, the lever G is held in the position shown in Fig. 4, by the engagement of the short arm of said lever with a pivoted catch, J, hung to a projection, k, on the plate H, the catch being weighted so as to retain the position shown in Fig. 4, the drum 1) of the spindle B being then in frictional driving-contact with the belt at. Vhen the lever G is in the position shown in Fig. 4, the spindle B is retained in the slot f by means of a lug, c, on the plate I-I, against which the spindle bears. The end it of the catch is beveled, as shown in Figs. 2, 3, and 6, and as the bobbin is filled with yarn the rearward movement of the spindle brings the rear end of the drum b into contact with said beveled end of the catch, which, as the movement continues, is pressed away from the spindle until the lever G is finally released from the control of the catch, when, owing to the descent of the weighted long arm of said lever, the spindle Bis raised, as shown in Fig. 5, so as to free the drum 1) from contact with the belt d and stop the rotation of the spindle. The movement of the lever G, when released from the control of the catch. J, is limited by the contact of a lug, t, on the same with the projection g of the plate H, and undue movement of the catch J is prevented by contact of the lug n with the projection 70 of the plate H. The catch will be self-locking on restoring the lever G to its former position, as will be readily understood on reference to Figs. 4 and 5. A special collar or flange on the spindle B may be provided for actuating the catch J, and a sliding catch actuated by a spring may, if desired, be used instead of the weighted and pivoted catch shown, and a spring may be used in place of a weight to actuate the lever G, (see Figs. 8 and 9;) but the construction shown is preferred. The spindle or pin of each conical roller F is carried by projections 19 on a plate, M, secured to the frame A by means of a bolt, N, adapted to a curved slot, 25, in the plate, this slot being such that the plate can be adjusted so as to vary the angle of the rolls F to suit the character of the conical end of the mass of yarn on the bobbin. The outer projection, 19, of each plate M has a lug, w, the lugs of the opposite plates projecting over and forming a bearing for the bobbin a, so that the usual fixed spindle-bearings on the frame are dispensed with. The yarn for each spindle is drawn from a hank, X, Fig. 1, the yarn passing first round a bar, 40, suspended by a rod, a2, and chain from a bracket, or, and thence around a pin, g on a lever, 3 on the frame to the guide-eye on the traverse-bar. The weight of the bar .2? tends to cause it to hang plumb, as shown in Fig. while the draft on the yarn tends to draw the bar in the direction of the arrow, a proper tension, dependent upon the weight of the bar, being thus exerted upon the yarn. There may be one of these suspended bars as for each hank X, or one bar may be used in connection with a number of hanks. The

long arm of the lever y carries the lower reel of the hank X, the upper reel being hung to a fixed bracket on the frame.

I claim as my invention 1. The combination of the lever G and the retainingcatch J with a winding-spindle carried-by the lever and having a projection for actuating the catch as the spindle is moved rearward, and with a frictional driving device for the spindle, as set forth.

2. The combination of the lever G with the retaining-catch J, having a beveled end, h, the spindle carried by the lever, and having a-projection adapted to actuate the catch, and a frictional driving device for the spindle, as set forth.

3. The combination of the weighted lever G, having a slot, f, with the weighted and pivoted retaining-catch J, the spindle adapted to the slot f and having a catch-actuating projection, and the frictional driving device for the spindle, as set forth.

4. The combination of the frame A and the bolts N with the rollers F and the plates M, carrying the said rollers, and having curved slots t, for the reception of the bolts N, as set forth.

5. The combination of the upper and lower hank-rollers, and the fixed bearing for the upper roller, with the suspended rod x and the lever y, carrying the lower hank-roller, and having a thread-guiding pin, 3 as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN H. CROWLEY.
